Apple has released the second public beta of the upcoming OS X Yosemite, but with no word about what might have changed. If you’re running the first public beta, get the new version from the Updates tab in the App Store app. You can still sign up for the public beta, and regardless, we recommend picking up a copy of Joe Kissell’s name-your-own-price “Take Control of Beta Testing Yosemite,” which provides complete details on preparing for, installing, and testing the Yosemite beta. follow link
Hide TextExpander in the Dock
If you don't want to see TextExpander's icon in the Dock and the application switcher, you can remove it. Just open TextExpander > Preferences > Appearance, and select Hide TextExpander Icon in Dock. You'll still be able to access TextExpander from its menubar icon.
